Medical Definition of White blood cell Medical Definition of White blood cell White blood cell: One of the cells the body makes to help fight infections. There are several types of white blood cells . The two most common types are the lymphocytes and neutrophils (also called polymorphonuclear leukocytes, PMNs, or polys). Lymphocytes are made in lymphoid tissue in the spleen, lymph nodes, and thymus gland.

Objective: Much of the study of microorganisms depends on its ability to grow in the laboratory, and this is possible only if suitable culture media are available for the growth of microorganism. A culture medium is defined as a solid or liquid preparation used for the growth, transport, and storage of microorganisms.

shake culture shake culture. A method for isolating anaerobic bacteria by shaking a deep liquid culture of an agar or gelatin to distribute the inoculum before solidification of the medium. A liquid medium in a flask that has been inoculated with an aerobic microorganism and placed on a shaking machine; action of the machine continually aerates the culture.

Growth medium A growth medium or culture medium is a solid or liquid or semi-solid designed to support the growth of microorganisms or cells, or small plants like the moss Physcomitrella patens. Different types of media are used for growing different types of cells. The two major types of growth media are those used for cell culture, which use specific cell types derived from plants or animals, and microbiological culture, which are used for growing microorganisms, such as bacteria or fungi.

Sputum Culture  [en EspaÃ±ol] A sputum culture is a test to find germs (such as bacteria or a fungus) that can cause an infection. A sample of sputum is added to a substance that promotes the growth of germs. If no germs grow, the culture is negative. If germs that can cause infection grow, the culture is positive.

Cell culture Cell culture technicians grow living cells in culture flasks, bioreactors, plates and other kinds of containers. The types of cells they grow can come from plants or animals.ome of the newer cell culture techniques allow stem cells to be grown in culture. Stem cells are special cells that can give rise to multiple cell types when given the proper kinds of hormones and growth factors. These cells are being investigated for possible medical treatments.

- Culture media are employed in the isolation and maintenance of pure cultures of bacteria and are also used for identification of bacteria according to their biochemical and physiological properties. The manner in which bacteria are cultivated, and the purpose of culture media, varies widely. Liquid media are used for growth of pure batch cultures, while solidified media are used widely for the isolation of pure cultures, for estimating viable bacterial populations, and a variety of other purposes. The usual gelling agent for solid or semisolid medium is agar, a hydrocolloid derived from red algae. Agar is used because of its unique physical properties (it melts at 100oC and remains liquid until cooled to 40oC, the temperature at which it gels) and because it cannot be metabolized by most bacteria.

White blood cell White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.All leukocytes are produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell.hite cells are found in the buff, a thin, typically white layer of nucleated cells between the sedimented red blood cells and the blood plasma. The scientific term leukocyte directly reflects its description.

NK cell cytotoxic T cell. A CD8+ T lymphocyte that can destroy microorganisms directly through the release of perforin and proteolytic enzymes. These cells are particularly important in the defense against viruses, rejection of allografts, and, possibly, new malignant cells. Synonym: CD8 cell; cytotoxic cel; killer T cell. See also: cell.

Techniques of Virus Cultivation 4.49 / 5  ( 544 ) Explant culture is rarely done. Cell culture is mostly used for identification and cultivation of viruses. 1  Cell culture is the process by which cells are grown under controlled conditions. 2  Cells are grown in vitro on glass or a treated plastic surface in a suitable growth medium. These are normal cells derived from animal or human cells. 2  They are able to grow only for limited time and cannot be maintained in serial culture. 3  They are used for the primary isolation of viruses and production of vaccine.

- Culture media. Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as agar or gelatin.
